Islamic ‘Revolution & Holy Defense Museum’ is designed to manifest a conceptual approach to the form of the museum while adhering to the design norms and standards that apply to the subject. The project’s site is adjacent to Imam Khomeini Holy Shrine. This was the main reason for the design team to consider a horizontal layout for the project, avoiding intruding heights in respect to the monumental shrine. The horizontal form stretching out on both sides of the entrance, on the other hand, is a conceptual reference to the 8years war. The horizontal layout is also a sustainable solution considering the desert climate of the site, and an environmentally and visually sustainable solution for avoiding intrusions in a vast desert view. The very solid material selection for the façade, contradicts the smoothness of the artificial lake and this also is a conceptual reference to the contradicting human feelings manifest during crises such as war. Using indirect sun light in most of the spaces and avoiding the direct ray in enclosed spaces, adheres to light standards applying to the design standards for a museum, and at the same time refers to human conditions during an imposed war, translated into a spatial quality and architectural language. A big challenge was to design the museum complex in 3 phases, so that any delay in the construction of the 3rd phase will not violate the wholeness of the first two phases. Open space museum parts, multiple accesses to the site, both pedestrian and vehicle, and monumental form are amongst other achieved design goals. The artificial pool has a good impact on the micro climate of the area especially in relation to impacting the cool breezes, and is designed in detail with the most environmentally friendly standards.
